High Pressure Forming (HPF) | Vacuum-/ Thermoforming | |
---|---|---|
Material temperature 温度 | Tg (Polycarbonate: 150 °C / 425 °K) | Melting (PC: 210 °C / 485 °K) |
Forming pressure 压力 | 90 bar / 1,300 psi | - 1 bar / 6-8 bar (100 psi) |
Material distortion 变形 | low | higher |
Precision (3D-shape) 形状精度 | Very high (<0.1mm) | less |
Precision (positioning) 定位精度 | High (+/-0.3-0.5mm) | less |
Repeatability 重复性 | High (process variables are fixed) | less |
